Warming Up To 2025: 1.37°C

These latest numbers imply 1.5°C of total global warming in just four years. 2.0°C of warming in 2049. It's coming on fast now. Here's the paper.

Our 2026 Indicators of Global Climate Change paper is out! We find that the human-induced warming was 1.37C in 2025, and the current rate of warming is 0.27C per year, on track to firmly pass 1.5C in about four years: essd.copernicus.org/...

    0.27C/year means 2.7C/decade? That sounds wrong... otherwise we'd have ~3C every 10 years or so. Am I misunderstanding?

    Ah. It's in the paper. "increasing at a rate of 0.27 [0.2–0.4] °C per decade over 2016–2025." - so ~2-4°C/Century. Scary.

    Yes, that C/yr looks like a typo; it should be C/decade.
